Embodiment 1

[0025] Such as figure 1 , 2 , 3, the electric locomotive roof provided by the embodiment of the present invention includes a metal roof 1 and an insulating composite material layer 3 covered on the metal roof. In the metal top cover 1, the position of the pantograph mounting seat forms a recess for carrying, gluing and lowering the height of the pantograph. The pantograph mount 5 is embedded in the insulating composite material 3 . The insulating composite material layer 3 is connected to the metal top cover 1 with an adhesive 4, and a layer of conductive paint 6 is coated on the lower surface of the insulating composite material layer 3, and the conductive paint 6 on the lower surface of the insulating composite material layer 3 is formed by a stainless steel plate 2 grounded. The leveling of the pantograph installation surface is achieved by adding stainless steel plate adjustment pads to the stainless steel plate 2.

[0026] There is a movable cover plate 7 under the p...

Embodiment 2

[0028] Such as Figure 4-7 As shown, the embodiment of the present invention provides an electric locomotive roof, including two insulating composite material layers 10, a foam material 12 is sandwiched between the insulating composite material layers, and the pantograph mounting seat 9 is pre-embedded in the insulating composite material layer. In the middle, each equipment mounting seat 14, 15, 16 is pre-buried in the middle of the insulating composite material or pasted on the bottom of the insulating composite material, and a steel wire mesh or conductive paint layer 11 is arranged outside the insulating composite material layer below. the

Abstract

The invention relates to a top cover of an electric locomotive body, wherein the top of the electric locomotive is provided with a pantograph region; the periphery of the pantograph region is provided with an insulation composite material layer; a pantograph installation seat is pre-buried at the center of the insulation composite material layer; and a layer for eliminating static or corona is installed outside the downmost insulation composite material layer. According to the invention, the electric locomotive and the electric motor unit can be used in special environments (such as high altitude regions and polluted regions); and the application regions of the electric locomotive and the electric motor unit are expanded.

Description

technical field [0001] The invention relates to a top cover of an electric locomotive body. Background technique [0002] Present electric locomotive, electric train unit top cover are all metal materials, not insulating. The current receiving system is installed on the top cover through insulators. Usually, according to the current distance between the top cover and the current receiving system, the insulators on the current receiving system can meet the insulation requirements. However, for a certain special environment, such as in high altitude areas, the original design cannot guarantee the insulation performance due to the deterioration of the air insulation performance. In this case, it is usually necessary to increase the insulation distance between the current receiving system and the top cover. However, due to the limitation of the rolling stock boundary, the method adopted is to compress the distance between the top cover and the rail surface, or to improve the c...
